Yes, probably. But is there any reason why you'd want to use radeonfb
rather than radeon?

I'll check with the debian-installer team if this is possible. Right
now the debian-installer is setup to use `radeonfb` (at least on
PowerPC) during the text-based installation.

So it seems there would be a risk moving from radeonfb to radeon, esp.
since Debian does not distribute (at least by default) the firmware
during installation: https://bugs.debian.org/826629#12.
I'll report the bug against radeonfb and see if I can provide a patch.

radeon should be able to offer the same functionality as radeonfb even
without firmware.
But saying so that functionality is usually rarely tested.
